4To all whom it may concern: i

Beit known thatwe, PAUL SCHNEIDER and HENRY TRENKAMP, of Cleveland, in the county Vof Guyaho'gaand State ot' 0hio,have invented a certain new and Improved in Vapor-Burner;

and we do hereby declare that the Following is a full, clear, and complet-e description thereof.

The nature of this invention relates to avapor-burnerforgasolinc-stoves. Saidburnerconsists of a gas-generator situated directly below thecombustion-chamber. Said chamber is put in communication with the generator by tubu lar conductors provided with a needle-valve. Within the combustion-chamber is a tubular cylinder, into which the gas for consumption is discharged, flowing therefrom over the top of' the tubular cylinder into the combustionchamber, as hereinafter more fully described, and illustrated by the accompanying drawings, making a part of this specitication,in which- Figurel is an external side view of the burner above alluded to. Fig. 2 is a vert-ical trailsverse section. Fig. 3 is a detached view.' Fig.

, 4 is a perspective view.

Like letters of reference refer to like parts in the several views.

As shown in the drawings, A represents a feed-pipe connecting the burner to an oil can or reservoir, constructed and arranged subst-antially in the same way as those in ordinary use in this class of stoves. Hence a detailed description thereof is not thoughtto be necessary in this place. To the upper end ofthe said feedpipe is secured a gas-generator, B, in open communication with the needle-valve chamberG by aconduit, D, and pipeE, formingapassage-way from the generator to the needle-valve chamber. Above the generator (and an integral part of the same) is a funnel-shape base, F. Said base, together with the perforated rim G, forms the exterior wall or shell of the combustion-chamher. Around the inner edge of the base F is formed a rabbet adapted to receive the lower edge of the ring G to prevent its lateral displacement from the base. Said ring and the base may be cast in one pieceinstead of being in two parts, as shownin the drawings. In the side of said base is ahole, in which isinserted a tube, H, which terminates about midway in the combustion-chamber and extends out therefrom in alignment with the needle-valvecham- I isa cover fitting closely the top of the ring,

as seen in Fig.2. y To theunderside of the cover l ber C, as shown in Fig. l. Said tube His se- I is attached, by hangers b, a cylinder, J, aydel tachedview of which is shown inxFig. 3. It will be observed that the lower end of the cylinder is close to the bottom ot' the base F, but not so close as to touch, whereas the upper end is not close tothe cover, there being a considerable space between the end ot' the cylinder and the cover. It will also be observed that there is an annular spacebetween the cylinder and the wall of the combustion-chamber, and that the tubcHterminatesin the said cylinder, there being an opening in the sideot the cylinder t'or the tube H to pass loosely through.

K is an oil-cup secured to the supply-pipe Aby 'a set-screw, c. The purpose of the said cup will presently be shown.

The practical operation of the burner is as follows: In order to start the burner a small quantity of oil is turned into the cup K from the base F of the combustion-cham ber, which oil is injected therein from theneedle-valve chamber. On opening the valve e for that purpose said chamber is filled with oil from the supply-pipe A, which iiows therefrom into the generator, thence into the needle valve chamber, from which it is injected through the tube H into the combustionchamber, or the cylinder J therein, under the end of which it runs into the chamber sufficiently to start the burner on ignition. The oil tlows from the combustion-chamber or ba se F through an orifice, d, Fig. 4:, andfalls upon the coi'iduitorextension D of thegenerator, and runs from tbepointd into the cup. The oil is prevented from running down the outside of the generatorB and leaking between the collarD ot' the catch-cup and the feed-pipe by a flange, d', projecting from the sides ofthe conduit. y Said ange is of no use, provided the collar D is litted tightly around the feed-pipe. The oil in the cup, when ignited, heats the generator and the conduit D, the conduit being heated by the burning oil in the extension K of the cup. The gas thus generated passesfrom the generatorin to theneedlevalve chamber, from whenceit escapes on open- IOO ing the needle-valve e'iuto the tube H and discharges inthe cylinder J. The gas passes up in the cylinder and oWs over the upper end thereof into the annular space N, from which itjissues through the perforations of thering G in jets of bright blue dames. The heat of the jets is conveyed down to the generator by the sides of tbe base F of' the combustion-chamber,` 'and continued in and about the generator for vaporizing. the oil therein when the oil in the( cupis burned out. The quantity ot oil supplied to the generator is regulated by a valve in the supply-pipe, (not shown in the drawings,) and.l of which valve A is the stem. Thevolumeof gas admitted to the combustion-chamber is regulated by the needle-valve, ot' which C is the stem.

The lines C indicate a hood covering the point of the needle-valve and the end of the tube H to prevent drafts of air from iiickering the flow of 'gas from the needle-valve to said tube H. Said hood is more clearly shown in Fig. 4.,

What We claim as our invention, and desirev to secure by Letters Patent, is-

1. In vapor-burners, the cover I, and depending therefrom a cylinder with open. ends,tl1e

lower end of which terminates near the bottom of the base F of the combustion-chamber andv the opposite end terminatingin the upper lpart of the combustion-chamber and terminating in a cylindertherein, and arranged in relation to and in combination With a needle-valve mechanism, substantially as setwforth, and for the purpose specified. Y

4. The' combination of the perforated ring G, the cup. and dependingcylinder, the 'base F, having the orifice dthe horizontal inductionpipe, andthe conduit provided withv a collar and point, substantially asand for thepurpose. .set forth.
